WILLIAM GEORGE LANE, OF PICTOU, CANADA.

COAL-DUM PING CAR.-

SPECIFICATION forming part of Letters Patent No. 501,148, dated July11,1893.

Application filed April 1l, 1893.

.To @ZZ whom it may concern: l

Be it known that I, WILLIAM GEORGE LANE, of Picton, in the Province ofNova Scotia, in the Dominion of Canada, have invented certain new anduseful Improvements in Coal- Dumping Cars; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, in which- Figure l, isa longitudinal vertical section of a hopper car showing the dumpingdoors closed. Fig. 2, is a like view showing the dumping doors Open, andFig. 3, is a transversevertical section showing the doors closed.

My invention has for its objeotto construct and operate a hopper car tocarry coal and adapted to dump the load instantly.

My inventionconsists in the construction and combination of parts aswill be hereinafter described and specified in the claims.

A, is the hopper of the car superposed on a car frame B, which ismounted on wheels C.

D, is the outlet of the hopper which outlet is closed by doors E, E',having ends l, 2, which are pivoted by pins or pintles 3, 4, to abearing F, secured to the car frame, and extending inwardly anddownwardly below the mouth or outlet of the hopper, whereby the doorswill shut from Opposite directions and when said doors are released,fall away from one another, clear of the Outlet of the hopper, to permitthe coal to have free and unbroken dump or fall from the hopper.

The doors E, E', are Operated simultaneously to open and close, by arock shaft G, journaled across the frame of the car and provided at theends with a lever H, to rock said shaft from either Or both sides of thecar, and said rock shaft carries radial arms J, J', extending inopposite directions. The upper end of the arm J, is' connected vto themost distant door E, by a rod K, having a loop 6, which travelsonaheaded pin orbolt 7, driven in or secured to the end l, of the doorE, and the lower end of the arm J', is connected to the nearer door E',by a rod K', which is piv- Serial No. 469.981. (No model.)

oted to the end 2,0f the door E', bya pin and eye 8. rPhe opposite endof the rod K' is provided with a loop 9, which travels on aheaded pin orbolt 10, driven into or secured to the arm J', near the lower end. Whenthe levers H, are operated in one direction, the rods K, K', pull andpush the doors open, and when moved in the opposite direction, the rodsK, K', act reversely and push and pull the doors closed. The loops atthe ends of the rods K, K', allow freedom of action to said rods to openand close the doors.

M, is a gravitating latch pivoted at one end to the outside of thehopper, immediately above the doors E, E', and said latch is providedwith a notch M', which engages lugs l2, 13, on said doors to keep themlocked, and said latch is lifted out of-contact bya cam 14, on rod K,engaging the latch when said rods K, K are pushed to Open the doors, thedoors then falling by gravitation.

I claim as my invention- A l. The combination with a car frame having ahopper A, of the doors E, E', having ends l, 2, pivoted to a bearing F,below the outlet ofthe hopper, a rock shaft G, journaled across thecarframe and carrying radial arms J, J', and rods K, K', connecting saidarms to the respective doors, whereby the doors are respectively pulledand pushed from the outlet of the hopper and pushed and pulled togetherby rocking said shaft by the levers H, as set forth.

2. The combination with a car frame B, having a hopper A, of the doorsE, E', having ends l, 2, pivoted to a bearing F, and provided with lugsl2, 13, the gravitating latch M, having a notch M', engaging said lugs,and the push rod K, connecting with one of said doors, said rod providedwith a cam 14, to lift the latch out of engagement to permit the doorsto open, as set forth.

. WILLIAM GEORGE LANE.
